The weekly food shop can be a major drain on finances. I always get nervous that I'm not getting the best deal on the things I buy. Could I be getting this tin of beans cheaper elsewhere?

Price comparison website My Supermarket aims to help shoppers get the best deal on their supermarket buy. The site compares prices at the main UK retailers, including Tesco, ASDA, Sainsbury's and Waitrose.

You can order your basket online, print your basket as a shopping list to take to your local supermarket or just use the site as a price comparison tool. The site claims that you will save an average of £17 every time you use it.
